Many believe the gang that stole gems, gold and cash worth £200million have been good for business.

They say tourists are pouring through the doors to quiz shop owners about the bank holiday raid at the Hatton Garden Safe Deposit building in central London.

Harry Karaca, manager at Channings, said: “I wish it had never happened but I think people have realised that we are here now. If anything it has been busier, people are interested.”

Another shop manager said: “We have not seen any negative impact, I think it may even help long-term.” Another worker said he had been told most of the safe boxes raided belonged to private customers rather than jewellery shops.

Police have released CCTV images of the gang wearing high-viz jackets and hard hats as they spent the weekend emptying safety deposit boxes.
